WATER HEATER.

Application filed Nbvember 6, 1922. Serial No. 599,271.

This invention relates to' improvements in water heaters.

Themain objects of the invention are: First, to provide in a. waterheater of t the coiled type an improved coupling and supporting meansfor the coils within the casing.

Second, to provide 'in a water heater an improved coupling member whichgreatly 1 facilitates the assemblin of the parts, avoiding the necessityor brazing and soldering.

Third, to provide an improved water I heater structure in which thecoils may be readily removed and replaced should occasion requires 7Further objects, and objects relating to structural details, willdefinitely appearfrom the detailed description to follow. I accomplishthe objects of my invention by the devices and means described in thefollowin specification. The invention is clearly %efined and pointedout. in the claims.

" 5 A structure which is a preferred embodiment of my inventionis;clearly illustrated in the accompanying drawing, forming a part ofthis application, in which: Fig. I is a side elevation of a water heater-80 embodying the-features of my invention, the same being shown mainlyj 1n conventional form.

Fig. II is a vertical central section through the casing.

85 i Fig. III is a detail view partially in horizontal section on a linecorresponding to line 3-3 of Fig. II. y y

Fig. IV is a detailsection on a line correspondin to line 44 of Fig.III.

0 Hi V 1s a detail section on a line correspon ing to line 5-5 of Fig.II.

In the drawing similar reference characters refer to similar partsthroughout the several views and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the casin of the heater, 2 thebase and 3 the top t ereof. The top is-provided with 6 a vent flue 4.The burner is conventionally illustrated at 5.' The heatingcoils 6 and 7are disposed one within the other, the wind of the coils being opposite.These coils are connected to the water discharge and supply pipes andare supported bythe couplings 8 and 9; The coupling 8 is provided withoppositely disposed arms 10 and 11 having coupling nuts '12 adapted toclamp the flange ends of the coils against the ends of the arms. Thisform 'of coupling bein old it is not detailed. The arms are dlsposeoppositely as stated and are of such length that one does not interferewith the manipulation ofthe coupling member of the other. The couplingmember 8 is disposed through an opening 13 provided therefor in the sideof the casing near its lower end and has stop lugs 14; which are clampedagainst the inner side of the casing by means of the nut 15, theprojecting end 16 of the coupling member being threaded to receive thenut and also the pipe coupling 17. Lugs 18 engaging recesses or notches19 in the edge of the opening 13 support the couplin member 8 againstrotative movement. T e coupling member 9 is provided with arms 20 and 21equipped with the coupling nuts 12, this coupllng member being disposedthrough the hole 22 in the top of the casing and being provided withlugs 14 which are clamped against the inner side of the easing by thenut 15, lugs 18 being provided to prevent rotative movement of thecoupling member.

The discharge pipe the projecting end of the coupling mem With thepartsthus arranged the coils are effectively supported. as well as beingconnected to the supply and discharge pipes and should occasion requirea coil may be renewed or removed for cleaning should it become clogged.v

The coils are connected to the couplings without the aid of brazing, asis general practice, and, in installing the heater all that is requiredis to attach the pipes by means of the usual standard plumbing couplingsor connections.

Myimproved couplings are very economical to produce and use of the sameresults in a'very decided economy in assembling in the heater and inattaching the heater to or installing infa house system.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
